EDX Markets

EDX Markets is an institutional cryptocurrency exchange that operates the world's only centrally cleared crypto trading venue, combining deep liquidity, transparent markets, low trading costs and ultra-low-latency matching-engine technology. It runs a spot exchange (EDX Markets), a perpetual-futures exchange (EDXM International, based in Singapore), a central clearinghouse with daily net settlement and bankruptcy-remote member accounts (EDXM Global), and a white-label crypto-as-a-service platform (EDX FlowConnect). Connectivity for members is delivered over the FIX protocol — FIX 5.0 SP2 order entry and drop copy plus FIX and binary (SBE) market data, transported over mutually authenticated TLS — rather than a public REST/OpenAPI. EDX is backed by institutional partners and was surfaced through the pantera-capital portfolio.

EDX Markets publishes 1 API on the APIs.io network. Tagged areas include Company, Crypto, Cryptocurrency, Digital Assets, and Exchange.

EDX Markets’ developer surface includes documentation, API reference, support, engineering blog, signup flow, pricing, authentication, and 13 more developer resources.
